### Changed

- [#2194](https://github.com/thanos-io/thanos/pull/2194) Updated to golang v1.14.1
- [#2136](https://github.com/thanos-io/thanos/pull/2136) store, compact, bucket: schedule block deletion by adding deletion-mark.json. This adds a consistent way for multiple readers and writers to access object storage.
Since there are no consistency guarantees provided by some Object Storage providers, this PR adds a consistent lock-free way of dealing with Object Storage irrespective of the choice of object storage. In order to achieve this co-ordination, blocks are not deleted directly. Instead, blocks are marked for deletion by uploading `deletion-mark.json` file for the block that was chosen to be deleted. This file contains unix time of when the block was marked for deletion.
